Winter has finally arrived in the Northeast, and it is making a serious splash.

We wanted a white Christmas, but that didn’t happen around here; Nature is making up for it now. We’ve had multiple storms this week complete with snow, sleet, ice and rain (sometimes all at once) and expect a significant snowstorm to hit this weekend.

That has me investigating weather reports, flexing my shoveling muscles, and generally catching up on all things snow. Here are a few of the interesting articles I found:

Science of Snow | National Snow and Ice Data Center

Snow forecasts are better than they used to be, and they continue to improve, but snow forecasting remains a difficult challenge for meteorologists. One reason is that during intense snows, the heaviest snowfall can occur in surprisingly narrow bands, and on a smaller scale than observing networks and forecast zones can see. Also, the extremely small temperature differences that define the boundary line between rain and snow make large differences in snow forecasts. This is part of the fun and frustration that makes snow forecasting so interesting.

“So a snowflake that was more than a foot across. Is that, like, even possible?”

How to Shovel Snow Safely – This Old House

Freezing temperatures often bring snow, sleet, and ice. And removing that messy wintry mix from your walkways and driveways is no easy feat. Here is the best way to shovel snow to prevent injury and lessen your workload.

What’s Wrong With This Snowflake? (transcript)

Koop thinks ice crystals are masterpieces of natural beauty. Unfortunately, he says, “This beauty is sometimes corrupted.”

Seeing Snowflakes As ‘Hieroglyphs from the Sky’ (transcript)

“It’s been said that snowflakes are like hieroglyphs from the sky…,” says Libbrecht, an astrophysicist and chairman of the physics department at the California Institute of Technology. “In the shape of the crystal is encoded the conditions under which it grew.”

Time to charge up our phones, laptops, power banks and car. Stay safe and warm!

It’s Monday, I’m back at work, and while things are moving along fine I’d be lying if I said I didn’t wonder what a day in space would be like instead. 

Let’s take a little break and go to Mars, shall we?

NASA’s Curiosity Rover Captures a Martian Day, From Dawn to Dusk – NASA Mars Exploration

Rover drivers normally rely on Curiosity’s Hazcams to spot rocks, slopes, and other hazards that may be risky to traverse. But because the rover’s other activities were intentionally scaled back just prior to conjunction, the team decided to use the Hazcams to record 12 hours of snapshots for the first time, hoping to capture clouds or dust devils that could reveal more about the Red Planet’s weather.

For me, the end of a year is a great time to think about the future. 

What did one of science fiction’s most acclaimed writers think about the future back in 1980, what’s changed, and which of his predictions have already come to pass?

Drrp

I prepped a post for yesterday and assumed I was all set, but didn’t actually get it scheduled into the correct slot. Drrp. So I’m posting an extra one today, and linking to a fascinating graphic on cognitive bias and the many (many) types of assumptions humans are prone to making.

Every Single Cognitive Bias in One Infographic

Science has shown that we tend to make all sorts of mental mistakes, called “cognitive biases”, that can affect both our thinking and actions. These biases can lead to us extrapolating information from the wrong sources, seeking to confirm existing beliefs, or failing to remember events the way they actually happened!

Life Skills

I spent a lot of time as a kid learning skills that were technically unnecessary for me, but would have been essential to my ancestors. Skills like weaving, making cough syrup or dyeing wool using local herbs, flint knapping, bow making, that sort of thing (yes, my parents were very tolerant!). One of the skills I never did manage (and I bet the local fire department was grateful) was making a fire using only friction.

If you’ve seen Tom Hanks try this in Castaway, you’ll know that it isn’t as easy as it looks. 

If this is the sort of thing that catches your attention, as it does mine, this article might interest you.

Lighting a fire using friction requires an understanding of some physics principles − but there are ways to make the process easier

Fire by friction is a testament to human ingenuity, contributing to the development of early technology and a later understanding of physics, chemistry and heat transfer.

Purr-fect

Oh look, NASA just sent the first Ultra-HD video through deep space using a laser communications system.

NASA’s Tech Demo Streams First Video From Deep Space via Laser

Me: Cool cool cool. It’s a test, right? 

Other Me: That’s right. 

Me: So this experiment marks the progress humanity has made in reaching out to the stars. I wonder which video NASA used?

Other Me: This one. I think it perfectly encapsulates the usefulness of laser technology in general, and where we are as a species right now in particular.

Ken Liu is one of our modern masters of speculative fiction. The first story of his that I read was “The Paper Menagerie,” “the first piece of fiction to win three genre literary awards: the Hugo, the Nebula, and the World Fantasy Award.”

So he’s pretty good.

He’s also been thinking about art, AI and the evolving relationship between them. Here’s his new story:

Future Science Fiction Digest – Good Stories

Clara’s favorite part of the workday is the very beginning.

She likes flipping the switches on the wall right inside the office entrance, all sixteen of them, different colors and laid out in two neat columns, like the console from an old NASA space capsule that she got to sit inside once on a school trip to DC. As she takes a sip of her latte, her right hand running up the wall, click-click-click, flipping one switch after another, she imagines herself turning on rocket engines, initiating a docking maneuver, venting some dangerous alien spores out the airlock.

The story is one of the many interesting pieces in The Digital Aesthete: Human Musings on the Intersection of Art and AI, edited by Alex Shvartsman with an impressive roster of authors.

Today’s software can only imitate art, but what about tomorrow?

Of Notes and Meteors

Did this post start out life as a path to a map of sci-fi story locations in space? It did, and then I realized that in my haste, I’d picked a draft I’d already posted before.

It happens, especially on days when one is juggling not one not two not three but four big projects, and one has absolute reams of notes in the “blog post ideas” folder.

So now I’m here with an update, still space-related but also experiential. It has to do with the Geminid meteor shower.

Bundle up and look to the sky: It’s time for one of the best meteor showers of the year

The shower will be at its peak on Wednesday night and early Thursday morning, though you’ll likely see some meteors in the nights before and after…

“The meteors will seem to shoot out of the constellation Gemini (hence the name) but could streak across pretty much any part of the sky,” Wiegert said. “So if you can find a dark place, with a good view of the sky in any direction, you could get a good view of the Geminids.”

Happy hunting!

Want to see a rare astronomical event tonight? (And really, why wouldn’t you?)

The extremely rare Betelgeuse occultation by asteroid (319) Leona

For a very short time, we will see the legendary Orion constellation without its famous, orange shoulder, as it will be in the distant future, once Betelgeuse will have exploded as a supernova and faded to black.

Hey, I like Orion! What’s this all about?

Watch an asteroid eclipse the puzzling red giant star Betelgeuse tonight live online

At at 8:17 p.m. EST Monday (Dec. 11) (0117 GMT, Dec. 12), an asteroid will pass in front of the curious red star Betelgeuse, eclipsing it from our vantage point here on Earth and blocking it from view for up to 15 seconds in an event known as an occultation. The asteroid is known as 319 Leona, a main belt object that orbits the sun between Mars and Jupiter. Shaped roughly like an egg, 319 Leona measures some 50 by 34 miles (80 x 55 kilometers) in size.

Here’s a link to live coverage of the event.

So Orion’s loss is temporary, and will also help scientists better understand both the asteroid’s shape and the star’s characteristics. No Tim Burton movie required!
